Release v1.29.0/v0.51.0/v0.5.0

Overview

This release is the last to support Go 1.21. The next release will require at least Go 1.22.

Added

• Add MacOS ARM64 platform to the compatibility testing suite. (#5577)
• Add InstrumentationScope field to SpanStub in go.opentelemetry.io/otel/sdk/trace/tracetest, as a replacement for the deprecated InstrumentationLibrary. (#5627)
• Make the initial release of go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. This new module contains an OTLP exporter that transmits log telemetry using gRPC. This module is unstable and breaking changes may be introduced. See our versioning policy for more information about these stability guarantees. (#5629)
• Add Walk function to TraceState in go.opentelemetry.io/otel/trace to iterate all the key-value pairs. (#5651)
• Bridge the trace state in go.opentelemetry.io/otel/bridge/opencensus. (#5651)
• Zero value of SimpleProcessor in go.opentelemetry.io/otel/sdk/log no longer panics. (#5665)
• The FilterProcessor interface type is added in go.opentelemetry.io/otel/sdk/log/internal/x. This is an optional and experimental interface that log Processors can implement to instruct the Logger if a Record will be processed or not. It replaces the existing Enabled method that is removed from the Processor interface itself. It does not fall within the scope of the OpenTelemetry Go versioning and stability policy and it may be changed in backwards incompatible ways or removed in feature releases. (#5692)
• Support Go 1.23. (#5720)

Changed

• NewMemberRaw, NewKeyProperty and NewKeyValuePropertyRaw in go.opentelemetry.io/otel/baggage allow UTF-8 string in key. (#5132)
• Processor.OnEmit in go.opentelemetry.io/otel/sdk/log now accepts a pointer to Record instead of a value so that the record modifications done in a processor are propagated to subsequent registered processors. (#5636)
• SimpleProcessor.Enabled in go.opentelemetry.io/otel/sdk/log now returns false if the exporter is nil. (#5665)
• Update the concurrency requirements of Exporter in go.opentelemetry.io/otel/sdk/log. (#5666)
• SimpleProcessor in go.opentelemetry.io/otel/sdk/log synchronizes OnEmit calls. (#5666)
• The Processor interface in go.opentelemetry.io/otel/sdk/log no longer includes the Enabled method. See the FilterProcessor interface type added in go.opentelemetry.io/otel/sdk/log/internal/x to continue providing this functionality. (#5692)
• The SimpleProcessor type in go.opentelemetry.io/otel/sdk/log is no longer comparable. (#5693)
• The BatchProcessor type in go.opentelemetry.io/otel/sdk/log is no longer comparable. (#5693)

Fixed

• Correct comments for the priority of the WithEndpoint and WithEndpointURL options and their corresponding environment variables in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#5584)
• Pass the underlying error rather than a generic retry-able failure in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#5541)
• Correct the Tracer, Meter, and Logger names used in go.opentelemetry.io/otel/example/dice. (#5612)
• Correct the Tracer names used in go.opentelemetry.io/otel/example/namedtracer. (#5612)
• Correct the Tracer name used in go.opentelemetry.io/otel/example/opencensus. (#5612)
• Correct the Tracer and Meter names used in go.opentelemetry.io/otel/example/otel-collector. (#5612)
• Correct the Tracer names used in go.opentelemetry.io/otel/example/passthrough. (#5612)
• Correct the Meter name used in go.opentelemetry.io/otel/example/prometheus. (#5612)
• Correct the Tracer names used in go.opentelemetry.io/otel/example/zipkin. (#5612)
• Correct comments for the priority of the WithEndpoint and WithEndpointURL options and their corresponding environment variables in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc and go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp. (#5641)
• Correct comments for the priority of the WithEndpoint and WithEndpointURL options and their corresponding environment variables in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#5650)
• Stop percent encoding header environment variables in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc, go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc and go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp (#5705)
• Remove invalid environment variable header keys in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc, go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc and go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp (#5705)

Removed

• The Enabled method of the SimpleProcessor in go.opentelemetry.io/otel/sdk/log is removed. (#5692)
• The Enabled method of the BatchProcessor in go.opentelemetry.io/otel/sdk/log is removed. (#5692)
